Sociocultural factors and the genetic diversification of Amazonian Indians: A brief overview

Abstract

Within SES categories in the United States, racial and ethnic minorities generally fare less well on a variety of health‐related indicators than do majority groups. Important differences exist within subgroups, however, and at present, these differences are poorly understood. In this paper we address Hispanic subgroup (Cuban American, Mexican American, Puerto Rican, and Central/South American) differences in utilization of prenatal care. Data from the 1986 and 1987 national Linked Birth/Infant Death files are used to assess patterns of prenatal care utilization across subgroups. Using Kotelchuck's Adequacy of Prenatal Care Utilization Index, we find that when controlling for other factors, Cuban American and Puerto Rican women are more likely to obtain adequate care than are Hispanic women of Mexican or Central/South American origin. Other factors important in understanding utilization patterns include marital status, education level, birthplace, and region of the country. We conclude with a discussion of the relatively weak link between prenatal care and birth outcomes and identify important cultural factors that may be important in understanding why this relationship is not stronger.
